Benefits of technology

"The present invention is about an electrical connector with spike protection. The invention provides secure protection against spikes and cannot be destroyed in error by the user when a connector is unplugged. The invention achieves this by using a plug-in attachment made of sheet metal or plastic sections that can easily be laminated or bent. The attachment can be in the shape of a funnel or a wider cylinder or cuboid, as long as the internal width is bigger than the plug to be plugged in. The method is economical, easy to apply, and can also be performed subsequently on building sites on existing systems."

Problems solved by technology

The metal or metalized connector housings must not come into contact with metal objects, since this results in interference (spikes) affecting the images when MR recordings are taken.
Connected connector pairs were also covered with shrinkdown tubing, which has the disadvantage that this was invariably destroyed when the connector was unplugged and was often not replaced by the user of the MR equipment.

Embodiment Construction

[0019]FIG. 1 shows an electrical connector 1 with a cable 2 attached thereto. The housing 3 of the connector 1 consists entirely of metal. On the end face of the connector 1 is the mating face 4, which in the example shown is in the shape of a matrix of contact sockets. On both sides of the female part of the connector are threaded holes, into which the screws arranged on a mating connector (not shown) can be inserted to secure the plug-in connection.

[0020]FIG. 2A shows a perspective view of a plug-in attachment 6, obliquely from behind. To facilitate handling of the plug-in attachment a knob 7 is attached to the back thereof to facilitate removing the plug-in attachment from the plug-in attachment 1 if shrinkdown tubing is shrunk on. FIG. 2B shows the plug-in attachment from the front. A plug 8 with pin contacts which is complementary to the female connector 4 can be seen. It is not essential for the plug 8 to be implemented in operational condition. It is also sufficient if only i...

Abstract

The present invention relates to an electrical connector with spike protection with an at least partially metalized housing which has a cable end and a plug end. A protective sheath made of dielectric material surrounds the entire connector and forms an apron extended out over the housing in the area of the mating face of the connector in the mating direction.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority of German application No. 10 2007 008 740.5 filed Feb. 22, 2007, which is incorporated by reference herein in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to an electrical connector with spike protection and a method for production of a spike protection for electrical connectors with at least partially metalized housings.BACKGROUND OF THE INVENTION[0003]Many electrical devices, including medical imaging devices such as magnetic resonance devices or medical computer tomographs, have a plurality of electronic components which are connected to one another by electrically conductive cables. Many of these cables are electrically shielded cables, such as coax cables, to prevent signals transmitted through the cables from being corrupted by electromagnetic interference (EMI). Electrical connectors on the ends of these cables frequently have a metalized housing which is conductively conne...
